The following describes in detail the use steps of a descaling andcleaning device for a condenser of a power plant in this article withreference to FIGS. 1 to 7:

At the beginning, the electromagnet 39 is energized to attract the maingear 36, so that the spline cavity 62 is splined to the spline keyboard44, the cavity 43 is disconnected from the spline cavity 62, and theslider 51 and the secondary slider 50 are located on the side near thecenter of symmetry At the limit position, the auxiliary electromagnet 59is powered to attract the slider 57 so that the bolt 60 is disengagedfrom the pin hole 63. Under the elastic force of the auxiliary tensionspring 28, the piston 64 is located at the limit near the center ofsymmetry. The equipment is placed in the pipes of the condenser.

During operation, the external water supply equipment sends water flowto the water turbine 14 through the water pipe 15, so that the waterturbine 14 drives the rotating shaft 40 to rotate, and then the waterflow in the water turbine 14 is conveyed into the piston cavity 17through the connecting pipe 13, and part of the water flow pushes thepiston 64 to be symmetrical away from The center side moves so that thewheel 18 abuts the inner wall of the pipe. At the same time, the motor37 is started. The motor 37 drives the motor shaft 38 to rotate. Themotor shaft 38 drives the main gear 36 through the spline connection ofthe spline keyboard 44 and the spline cavity 62, so that The main gear36 drives the connecting rod 53 to rotate through the sliding keyconnection of the fixed shaft 55 and the sleeve 54. The connecting rod53 drives the slider 51 to move away from the center of symmetry throughthe slider 52, and pushes the auxiliary slider 50 and The push rod 30moves to the side far from the center of symmetry, so that the scraper29 abuts against the inner wall of the pipe, and then the motor 37 stopsand the electromagnet 39 loses power. Under the action of the springforce of the tension spring 41, the main gear 36 moves to the right, sothat The spline cavity 62 is disconnected from the spline keyboard 44.The spline cavity 62 is splined with the spline wheel 42. At the sametime, the main gear 36 is meshed with the ring gear 45. The shaft 40 isconnected to the spline of the spline cavity 62 through the cavity 43.Connection The main gear 36 rotates, and the main gear 36 rotates thering gear 45 and the turntable 31 through the meshing connection,thereby driving the scraper 29 to rotate and remove dirt on the fixedinner wall.

After the cleaning of thepipe is completed, the motor 37 reverses so that the push rod 30 and thescraper 29 move to the side close to the center of symmetry. After that,the motor 37 stops and manually pushes the wheels 18 and the piston 64to the direction. Moving near the center of symmetry, the power loss ofthe auxiliary electromagnet 59 causes the slider 57 to move to the left,and the pin 60 abuts with the pin hole 63, restricting the pistonchamber 17 to move up and down, thereby achieving the expansion andcontraction of the device and convenient storage.

The beneficial effect of the present invention is that the presentinvention is a pipeline robot. The telescopic movement mechanism canautomatically extend under the drive of water flow, so that the walkingwheel can automatically contact the inner wall of the pipeline, and thedescaling mechanism can realize the scraper under the drive of themotor. Automatic expansion and contraction, so as to automatically adaptto the inner diameter of the pipeline, and at the same time, the turbinein the equipment is rotated by external water supply to drive the bladeto rotate to achieve the descaling of the inner wall of the pipeline.Thus, walking along the inner wall of the pipeline is achieved, and thenthe water stream is sprayed through the water spraying mechanism,spray-washes the pipeline after descaling, and flushes the dirt in thepipeline to the outside, thereby realizing the cleaning of the interiorof the pipeline. It can clean and descale the inner wall of thecondenser pipe, effectively improve the descaling effect of thecondenser pipe, and increase the service life of the condenser.
